In a Harsh Environment, High Industrial Standards are Necessary

With IP40 Durable Aluminum housing and fanless design also provide efficient heat dissipation. 28-por Industrial Managed PoE Network Switch provides a high level of immunity against electromagnetic interference and heavy electrical surges, usually found on plant floors or curb-side traffic control cabinets. It also possesses an integrated power supply source with a wide range of voltages (9 to 56V DC) for worldwide high availability applications requiring dual or backup power inputs. Indeed, The design of the switch ensures operates in Harsh Environment.

28 Port Industrial PoE Network Switch with Advance L2+ Features

With a 4xGigabit Combo Port (SFP/RJ45), the 28-Port Industrial Managed PoE Network Switch can handle extremely large amounts of data in a secure topology linking to an industrial backbone or high-capacity servers. The FR-9M3424P is capable of providing non-blocking switch fabric and wire-speed throughput.

The 28-port Industrial Managed PoE Ethernet Switch series allows the administrator to conveniently boost network efficiency by manually configuring Layer 3 IPv4/IPv6 VLAN static routing. FR-9M3424P supports redundant ring technology and features a strong, rapid self-recovery capability to prevent interruptions and external intrusions. In addition to using advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching), Spanning Tree Protocol, and redundant power input systems, it enhances system reliability and uptime in harsh factory environments.

Industrial PoE Network Switch Compliant with IEEE802.3af/at PoE+ Standards

Port 1-24 complies with IEEE802.3af/at standard. Another critical point is it can automatically detect and recognise the power devices that meet the standard and supply power through the network cable. Being the PoE management for CCTV surveillance, wireless and VoIP Networks FR-9M3424P features the following special PoE management functions: PoE PD-alive check, Schedule power rebooting, PoE operation schedule, PoE usage monitoring, PoE port power feeding priority…

Take care of the 28 Port Managed Industrial Switch Anytime and Anywhere

28-port Industrial Managed PoE Network Switch allows various network management methods, such as the Cloud(MQTT), WebGUI, CLI and NMS. The notion of easy to use, particularly with no additional hardware investment and installation. Industrial Network Switch can deploy centralised management, Layer 2 to Layer 4 QoS, Bandwidth allocation, real-time monitoring, etc.

Both SSH2.0 and HTTPS/TLS protocols are utilized to provide robust protection against network threats. It includes a range of cybersecurity features such as DHCP Snooping, IP Source Guard, ARP Inspection Protection, 802.1x port-based and MAC-based network access control, user hierarchical management, SNMPv3 authentication, and so on to complement it as an all-security solution. The 28-Port Managed Industrial PoE Network Switch administrator can now construct highly-secure corporate networks with considerably less time and effort than before.
